Age at time of event: (b)(6) or older.(b)(4).Device evaluated by manufacturer: the device was returned for analysis.A visual inspection was performed.The device has the guidewire broken by tension overload near to the distal section, 327 cm from the proximal section, also the body is kinked.The distal section was not returned.The overall length and outer diameter of distal tip couldn't be measured due to the device condition.The outer diameter of distal section end near the broken section is 0.0054 inch.The outer diameters of middle of the device and proximal section are within specifications.The batch number is unknown and the manufacturing records for the complaint device could not be reviewed.The most probable root cause is operational context as device performance was limited due to anatomical procedural factors.(b)(4).
